Chemistry Test 4

QuestionAnswer
How do you tell if a molecule is polar? By drawing a Lewis diagram and one end is positive and the other negative
How do you tell if a molecule is non-polar? By drawing a Lewis diagram and both ends are symmetrical
What is an inter molecular force? They are found between molecules and hold substance together
What force is in both polar molecules and non polar? Dispersion
What is a dispersion force? A weak inter molecular force in both polar and non polar substances. It is due to the repulsion of the electrons and protons in 2 molecules
What is a dispersion force also known as? London Force
What is a dipole-dipole force? A force that keeps polar molecules together. These are the attraction of the positive to the negative end.
What are hydrogen bonds? A stronger version of dipole-dipole forces. It is when hydrogen bonds with O, F and N. It is due to the large difference in electro negativity
What breaks when a compound dissolves in water? The intermolecular forces
What happens to the boiling point when the intermolecular forces get stronger? The boiling point rises because the intermolecular forces are harder to break
What is a solute? A compound that dissolves into another substance
What is a solvent? A solution that dissolves another compound
